Frankly, I'm not bothered about the ratio of heals to DPS actions.
The problem here is when I'm sat there mindlessly pressing the same button for nigh 30 seconds straight, frequently with only a dot refresh to break up the monotony.
Imagine if SE released a new DPS job and it's peak gameplay was pressing the same button 10 times in a row. People would lose their minds over it. Yet it's the accepted norm for healers.
